Claims (1)

Способ отработки крутых пластов, включающий подготовку подэтажей проведением верхних и нижних подэтажных штреков с формированием охранных целиков, бурение скважин в подэтаже, взрывную отбойку угля на охранный целик с последующим погашением охранного целика и выпуском угля, отличающийся тем, что при подготовке подэтажей соответственно нижние и верхние подэтажные штреки соединяют углеспускными промежуточными печами, а охранный целик формируют над нижними подэтажными штреками проведением компенсационного штрека, из которого бурят скважины до верхних подэтажных штреков с последующей одновременной взрывной отбойкой угля в блоке на охранный целик, а погашение охранного целика производят буровзрывной отбойкой угля одновременно по всей длине блока на установленный на длину вынимаемого блока на нижнем подэтажном штреке конвейер, с помощью которого осуществляют транспортировку угля к углеспускным промежуточным печам.A method of working out steep seams, including preparing sub-floors by conducting upper and lower sub-floor drifts with the formation of guard pillars, drilling holes in the sub-floor, blasting the coal into a guard pillar, followed by paying off the guard pillar and releasing coal, characterized in that when preparing the sub-floors, the lower and upper sub-floor drifts are connected by coal-run intermediate furnaces, and a security pillar is formed above the lower sub-floor drifts by conducting a compensation drift, from which wells are drilled dinners to the upper sub-floor drifts with the subsequent simultaneous explosive breaking of coal in the block for the guard pillar, and the guard pillar is extinguished by drilling and blasting the coal at the same time along the entire length of the block to the conveyor installed on the length of the block to be removed on the lower floor drift, with which coal is transported to the coal discharge intermediate furnaces.
